@rochus Tried to compile on Arch Linux with your patch today. Found out that Gazebo still needs one patch in gazebo/rendering/RenderEngine.cc at line 427:

+++
#if (OGRE_VERSION >= ((1 << 16) | (11 << 8) | 0))
    plugins.push_back(path+"/Codec_EXR");
    plugins.push_back(path+"/Codec_FreeImage");
#endif

    plugins.push_back(path+"/RenderSystem_GL");
    plugins.push_back(path+"/Plugin_ParticleFX");
    plugins.push_back(path+"/Plugin_BSPSceneManager");
    plugins.push_back(path+"/Plugin_OctreeSceneManager");

Plus you need to use asp export ogre to get the PKGBUILD of Ogre 1.11 and change the cmake options:

  cmake .. \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DOGRE_BUILD_DEPENDENCIES=FALSE \
    -DCMAKE_BUILD_TYPE=RelWithDebInfo \
    -DOpenGL_GL_PREFERENCE=GLVND \
    -DOGRE_BUILD_PLUGIN_FREEIMAGE=TRUE

Confirmed that Gazebo 9.0.0 works seamlessly after these patches.

GPereira, I believe that ogre and ogre3d are the same. It appears that aur/ogre3d is ogre locked to version 1.10.11, the other ogre packages have their corresponding version number in the package name (e.g. aur/ogre-1.8, aur/ogre1.9, etc.).

The issue with gazebo and ogre is, that ogre 1.11 introduced several API breaking changes. I tried to follow all the changes in the ogre documentation and apply them to gazebo. I came up with the following PKGBUILD and patch file, with which gazebo compiles fine (excepted for a vast list of deprecation warnings, which I ignored). I didn't have any time yet to test if the compiled version runs fine at all, I was merely interested in compiling it.

PKGBUILD: https://gist.github.com/rochus/547b26bc85a39195e3d1833280798855 ogre-1.11.patch: https://gist.github.com/rochus/003b156bcc8368c8c353be12b748986e gazebo issue: https://bitbucket.org/osrf/gazebo/issues/2475/gazebo9-compile-error-with-ogre111

Nimoab, is ogre being replaced for ogre3d? is that it? Their website leads to that conclusion but I am not so sure

@al3xst I solved that problem by installing the AUR ogre3d package (https://aur.archlinux.org/packages/ogre3d/) and modifying the dependency in the gazebo's PKGBUILD. Also, the ogre3d package had to be compiled without the C++11 support. After rebuilding everythin, I also had a shadow issue. In the end I solved my problem compiling the ogre3d package with these options (don't know if they're all necessary though, especially TESTS and SAMPLES are certainly not, but I wanted to make sure Ogre was working properly before compiling gazebo):

cmake -G"Unix Makefiles" \
        -DOpenGL_GL_PREFERENCE="GLVND" \
        -DOGRE_BUILD_SAMPLES=ON \
        -DOGRE_BUILD_DEPENDENCIES=OFF \
        -DOGRE_BUILD_TESTS=ON \
        -DOGRE_BUILD_COMPONENT_RTSHADERSYSTEM=ON \
        -DOGRE_BUILD_COMPONENT_VOLUME=ON \
        -DOGRE_BUILD_TOOLS=ON \
        -DOGRE_CONFIG_DOUBLE=OFF \
        -DOGRE_INSTALL_SAMPLES=OFF \
        -DOGRE_CONFIG_THREAD_PROVIDER=std \
        -DOGRE_USE_STD11=OFF \
        -DCMAKE_INSTALL_PREFIX=/usr \
        "../${_pkgname}-$pkgver/"

ffmpeg also got updated this morning and I had a similar problem, but with libavcodec.so.57. I coudln't rebuild the gazebo package this time because the name of some constant changed in avcodec.

To rebuild gazebo, I had to patch and rebuild the package ignition-common first, then I could patch and rebuild gazebo

Here are the patches I made:

• gazebo: https://pastebin.com/5b2zzYAz
• ignition-common: https://pastebin.com/Gsqi6J6R

Hope it helps.

ogre got updated to version 1.11 but gazebo tries to load explicitly version 1.10.11 of all ogre libraries, so gazebo fails to start right now.

Interesting. Thanks for the feedback.

@racko, it seem missing the dependence of gxlinfo or python-opengl package in my machine, so after I installed the package listed before, gazebo could be installed successfully.

But I can't reproduce the problem after I remove the gxlinfo & python-opengl and reinstall gazebo package.

Check https://bitbucket.org/osrf/gazebo/issues/2059/fail-to-build-current-gazebo-git for more detail discuss.

Could you check the terminal output? I fear that CMakeError.log is not helping. I find

Determining if the function pthread_create exists in the pthread passed with the following output:

in CMakeOutput.log and

Determining if the pthread_create exist failed with the following output:

in CMakeError.log after a successful build.

Hello,

Thanks for mantaining this package!

I try to use yaourt to install this package, but fall through minor issues when build gazebo.

The CMakeError.log as follows

Determining if the pthread_create exist failed with the following output:

I guess add flag or find_package(Threads) in the CMakeLists.txt in the src directory should fix the problem, but it doesn't.

Is there someway to solve this issue. I have no idea how to search it by google now.

Best regards,
